Abstract: In one example embodiment, a light emitting device includes a transparent substrate and a transparent electrode on the transparent substrate, the transparent electrode comprising at least two transparent electrode layers, the at least two transparent electrode layers being successively stacked and having different refractive indices, the refractive index of one of the at least two transparent electrode layers that is closer to the transparent substrate being higher than the refractive index of the other one of the at least two transparent electrode layers. The light emitting device further includes a light emission layer on the transparent electrode and a reflective electrode on the light emission layer.
